Which has maximum bond angle CHF3 chcl3 chbr3 all have maximum bond angle?
Since we know that the size of the halogens increases in the following order: Br> Cl> F. Bigger the size of the atom, more is the space the electrons has occupied and more is the repulsions between two atoms. Hence, more is the bond angle.
What is the angle between CHF3?
The molecule of fluoroform(with tetrahedral shape CHF3 molecular geometry) is tilted at 109.5 degrees bond angle of F-C-H.
Which has the maximum bond angle?
NH+4 has 4 bond pairs and no lone pairs and is sp3 hybridized with the geometry and shape both being tetrahedral with a bond angle of 109.5o and so it has the highest bond angle among the four.
What is the bond angle of iodoform?

What is the bond angle of CHBr3?
Molecular Geometry Notation for CHBr3 Molecule :
| Name of Molecule | Bromoform or tribromomethane |
|---|---|
| Electron geometry of CHBr3 | Tetrahedral |
| Hybridization of CHBr3 | sp3 |
| Bond angle (Br-C-H) | 109.5º degree |
| Total Valence electron for CHBr3 | 26 |
Which is incorrect order of acidic strength CHF3 CHCl3 CHBr3?
The acidic strength order is, CHCl3>CHF3>CHBr3>CHI3.
What type of bond is CHF3?
CHF3 : dipole – dipole interaction.
What show has the highest hydrogen bonding?
Since, F is most electronegative and has smaller size, HF shows maximum strength of hydrogen bond.
How many double bonds does CHBr3 have?
The CHBr3 molecule has a tetrahedral molecular geometry because there is no electrical repulsion between the lone pairs of electrons in bromine and four bond pairs(C-H and three C-Br) of the CHBr3 molecule. Lewis structure of CHBr3 has dot electron representative structure.
What is the most shape of CHBr3?
The CHBr3 molecule has four pairs of electrons around the Carbon atom. Bromoform has the shape of a Trigonal Pyramid.
Which is more acidic CHCl3 or CHBr3?
Here, only CCl3- has effective backbonding and hence the negative charge partially gets stabilised by back donation to the vacant 3dπ orbitals of Cl. Thus, CHCl3 is a stronger acid among them due to 2pπ-3dπ back bonding. So, CHF3 is a better acid than CHBr3, and the least acidic isCHI3.
Why is CHCl3 a stronger acid than CHBr3?
Thus, CHCl3 is a stronger acid among them. The acidic strengths of the other two csn be compared their inductive effects. F is very electronegative and hence stabilises the negative charge on the C atom. So, CHF3 is a better acid than CHBr3.
Why is the bond angle in PCl3 greater than PF3?
The bond angle is smaller for P F 3 ( 97.7 0) than for P C l 3 ( 100 0) in accordance with less electronegativity of C l than F so bond pairs are more closer to central P atom in P C l 3 hence bond angle in P C l 3 is greater. Also, the fluorine- fluorine repulsion is less than chlorine – chlorine repulsion.
Why does NH3 have a higher bond angle than Nf3?
Because s- orbitals of the same Orbit are lower in energy than p-orbitals, s-electrons are therefore more tightly bound and the “looser” p- electrons are more easily attracted by more electronegative ligands (groups or atoms). Increasing s-character leads to a larger bond-angle. Hence, N H 3 has greater bond angle than N F 3.
What is the bond angle of AsBr3 ASCL3 and AsF3?
All the three compounds i.e. AsBr3, AsCl3 & AsF3 have same geometry, same hybridisation and same shape, and due to the presence of lone pair on Arsenic the bond angle of these compounds is less than 109.28″.
